Quick and easy P5 performance upgrade

[Mike]

Hi all,

I have a standard P5. What are the simplest, and cheapest, ways to provide some extra power without bolting on a turbo or something?

Many thanks,

Michael.

Foo foo valve

Good for 20 or so HP

Racing Beat cat-Back exhaust: 5 hp

Cold Air Intake: 2-3 hp

Both at the front wheels.

If you could find some camgears and adjust the timing...

relatively quick easy and inexpensive, but you aren't going to get giant gains from them.

best bang for the uck, without going turbo, is going to be replacement high compression pistons. the pistons will give you about a 20hp gain AT THE WHEELS! not exactly quick and easy, though.

Actually I disagree...best N/A bang for the buck (ignoring quick and easiness) is a nice port and polish of all the internals. Assuming you already have good flow (intake and exhaust, even headers) than that should add every bit as much as adding higher comp. pistons...of course doing both wouldn't be a bad idea either...

Also which pistons give us 20whp? The 10.5s? That's not bad...

chdesign was able to gain 35 to 40 horses to the wheels with his NA setup (cam gears, HC pistons, int/exh cams).

I had these in my FS-ZE engine, and I did not see a big gain because that alone will not net you much without tunning.

So a port and polish might net even more

Thanks everyone!

It sounds as though a cold air intake should be the starting point, with a bypass valve coz I don't fancy a load of winter rain getting sucked into my engine!

All the other stuff sounds good, just either expensive or complicated :-(

Maybe a better exhaust will also be on the cards...

All the best,

Mike.
